What the Sound and Noise Detector app does

Sound and Noise Detector is a sound level meter for Android. It shows the loudness of the sound around you in decibels, and it is built around live readings rather than a single snapshot.

The developer, GeniusTools Labs, describes it for personal use, for education and for research. It is listed under Tools and rated for everyone.

Live decibel readings and level monitoring

The main screen reports decibel (dB) values in real time. The listing says the readings are precise, but it gives no detail on how that is measured.

Because the readings update as they happen, you can watch a room or a site and see how the level rises and falls. That suits checking whether a space is getting louder over time.

Alarm limits and loud-sound notifications

You set an alarm limit at a decibel level of your choice. When the sound passes that level, the app sends a notification.

This works in the background as a warning, so you do not have to keep the readings on screen to know a sound has gone past your threshold.

Finding the source of a noise

The listing says the app can help pinpoint the exact source of a sound. It gives no further detail on how this works or how accurate it is.

Combined with the live readings, this is the part of the app aimed at finding out which noise is causing a problem, such as machinery or traffic.

Protecting hearing and checking noise pollution

The listing names three main uses: protecting your hearing from harmful levels, identifying and reducing environmental pollution, and complying with regulations.

Students and researchers are named as users too, as are people who simply want to know how loud their surroundings are.
